I like my Samsung HW-E450... The sound is not as punchy as some soundbars and speaker setups I have heard, but, to me it sounds deceptively warm and natural when you turn off the EQ presets and 3D sound. The bass passing through to the subwoofer is way too heavy for me at 0 so I turn it down to -4 where it is just fine for my subwoofer placement.
I recognise that there are better sounding soundbars than the samsung out there, but for the price I paid ($240), I think I got good value.
The one thing with the samsung is the anynet+ function doesn't seem to be compatible with many other tv manufactures systems. This means that you may not be able to control the volume of the soundbar with your tv remote if you own a tv made by LG, Panasonic, etc...
